Newtons laws

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as the formula F = m * a.

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What does the term 'inertia' mean?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A passenger in a car lurches forward when the car suddenly stops.

Front

What is an example of Newton's 2nd Law in action?

Back

Pushing a shopping cart harder makes it accelerate faster.

Front

What is an example of Newton's 3rd Law in action?

Back

When you jump off a small boat, the boat moves backward as you move forward.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What happens to an object when no net force acts on it?

Back

It will maintain its current state of motion, either at rest or moving at a constant velocity.
